- 9 BY MW FM United States Patent 2,774,970 FACE SHIELD Rudolf Du Bois,Alliance, N. J. Application December 20, 1954, Serial No. 476,331 4Claims. (Cl. 2-9) The present invention relates to new and usefulimprovements in face shields for various purposes and has for itsprimary object to provide, in a device of this character of the typecomprising a supporting frame and a protective sheet, novel means forremovably securing said sheet in position on said frame.

Other objects of the invention are to provide a face shield of theaforementioned character which will be comparatively simple inconstruction, durable, compact, of light weight, attractive inappearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawing,wherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a perspective view of a face shield constructed inaccordance with the present invention;

Figure 2 is a view in horizontal section, taken substantially on theline 22 of Figure 1;

Figure 3 is an enlarged fragmentary horizontal sectional view through anend portion of the device; and

Figure 4 is a view in horizontal section showing a slight modification.

Referring now to the drawing in detail, it will be seen that referencecharacter 5 designates generally an open frame of plastic or othersuitable material. The frame 5 includes an arcuate bar 6 comprising adownwardly or reversely bowed intermediate portion 7 having formedintegrally therewith depending nose pieces 8. Temples 9 are pivotallymounted on the rear of the end portions of the bar 6, as at 10.

Formed integrally with the end portions of the bar 6 and projectingforwardly therefrom are lugs 11. As illustrated to advantage in Figure 3of the drawing, the lugs 11 include inwardly and forwardly curvedtongues or fingers 12.

Removably mounted on the frame 5 is a protective sheet or panel which isdesignated generally by the reference character 13. The sheet 13 is ofsubstantially the shape shown and said sheet, which comprisesdistinctively and attractively colored marginal portions 14, is of asuitable transparent, resilient material, preferably a plastic. Thesheet 13 is provided in its upper portion with transversely spacedopenings for the reception of the lugs 11 for removably mounting saidsheet on the frame 5. Further, the sheet 13 is engageable under tensionbeneath the tongues 12 for retention thereby on the lugs 11.

It is thought that the manner in which the shield is assembled and usedwill be readily apparent from a consideration of the foregoing. Briefly,the openings 15 in the normally flat sheet 13 are spaced a greaterdistance apart than the distance between the lugs 11. To mount the sheet13 on the frame 5, said sheet is buckled or bowed forwardly on itsvertical or longitudinal axis and sprung under the retaining tongues 12onto the lugs 11. In this manner the bowed or buckled resilient sheet 13is tensioned or maintained in engagement with the tongues 12 by itstendency to expand or resume its normally flat condition. The marginalportions of the sheet 13 around the openings 15 are also distinctivelyand attractively colored to more sharply define said openings andfacilitate engaging the lugs 11 therein.

"ice

In the modification of Figure 4 of the drawing, lugs 16 of separatematerial are mounted on the end portions of the bar 6 and extendtherethrough. The lugs 15 comprise integral fingers or tongues 17,similar to the tongues 12, which retain the resilient sheet 13 inposition on said lugs. Then, the temples 9 are pivotally mounted on therear end portions of the lugs 16, as at 13. In other respects, this formof the invention is substantially similar in construction to theembodiment of Figures 1, 2, and 3 of the drawing.

It is believed that the many advantages of a face shield constructed inaccordance with the present invention will be readily understood, andalthough preferred embodiments of the device are as illustrated anddescribed, it is to be understood that changes in the details ofconstruction may be resorted to which will fall within the scope of theinvention as claimed.

What is claimed as new is as follows:

1. A shield of the character described comprising; a frame for mountingon the nose of a wearer, lugs on the end portions of said frame, and aresilient sheet having spaced openings therein for the reception of thelugs for mounting said sheet on the frame, the openings in the sheetbeing spaced a greater distance apart than the lugs for bowing andtensioning said sheet for frictionally securing the same on said lugs.

2. A shield of the character described comprising; a frame for mountingon the nose of a wearer, lugs for bowing and tensioning said sheet whenit is engaged with said lugs on the end portions of said frame, aresilient sheet having spaced openings therein for the reception of thelugs for mounting said sheet on the frame, and inwardly directed tongueson the lugs engageable with the sheet for retaining said sheet on saidlugs, the openings in the sheet being spaced a greater distance apartthan the lugs.

3. A face shield of the character described comprising; a framecomprising a bar for mounting on the nose of a wearer, temples pivotallymounted on the end portions of said bar, integral lugs projectingforwardly from said end portions of said bar, a resilient, transparentprotective sheet removably mounted on the frame, said sheet havingspaced openings therein for the reception of the lugs, and inwardlyprojecting tongues on the lugs for anchoring the sheet thereon, saidsheet being normally flat and transversely bowed when mounted on theframe, the openings in said sheet being spaced at greater distance apartthan the lugs.

4. A face shield of the character comprising; a frame for mounting onthe nose of a wearer, said frame including a bar, lugs extending throughthe end portions of said bar, temples pivotally mounted on the rear endportions of said lugs, a resilient, transparent protective sheetremovably mounted on the bar, said sheet having spaced openings thereinfor the reception of the forward end portions of the lugs, and inwardlyprojecting tongues on said forward end portions of said lugs engageablewith the sheet for anchoring same on said lugs, the openings in thesheet being spaced a greater distance apart than the lugs for permittingsaid sheet to be bowed and engaged under tension with said lugs.
